After the Invasion of the Phlanax, humanity started to rebuild. Alchemax had found Steve Rogers frozen after the Heroic Age and was later thawed out and explained how the Heroic Age ended. Miguel had found Thor's Hammer and gave it to Steve. Even though he refused at first, he decided to take the Hammer. Later on, The Watcher needed all of Earth's Mightiest Heroes to destroy the barrier with the sacrifice of the Watcher and Steve being frozen again and gave the hammer to Miguel.
